研究了用于DNA传感应用的阳离子带电树枝的pH响应性。在碱性条件下，第一代和第二代酰胺树枝状分子C1和G2形成水凝胶，但在酸性条件下水凝胶恢复到流体状态，这一过程是完全可逆的。此外，稀释后的Cl、G2和G3溶液的荧光对pH值也表现出很高的敏感性。
The pH responsibility of cationic charged dendrons, which were previously synthesized for DNA-sensing applications, was investigated. The first and second generation amide dendrons Cl and G2 formed hydrogels under basic conditions, but the hydrogel returned to the fluid state under acidic conditions; this process was completely reversible. In addition, the fluorescence of the diluted Cl, G2, and G3 solutions also showed a high sensitivity to the pH value.
